I edited this question once (edit 1) which was again edited (improved - edit 2) by user1729. I later found a more apt question title and edited the question again (edit 3) just to change the title of the question (without paying attention to the body).
To my surprise, I found that my latest edit (edit 3) was done over my previous edit (edit 1), which included some mistakes that was corrected by user1729. Can you please suggest why this happened because there is no way I can revoke my edit and correct it again.
I want to know if this is how it works or if it's a bug ?
Note: FYI, I edited the question again to include the formatting (that was lost due to my previous edit) done by user1729.
